COAL POWER Direct

Conventional wisdom tells us that the key to good boiler combustion requires carefully balancing the fuel-air ratios across all the coal pipes. Recent tests show that the uniformity of the burner-to-burner stoichiometries—not balanced pipe-to-pipe fuel flow distributions—dictates combustion uniformity.

Many coal-fired power stations built before 1980 were designed for handling relatively easy-handling lump coal. If your plant’s bins, bunkers, and silos aren’t up to dealing with today’s range of more variable coal properties, this case study shows one way to minimize coal flow problems.

President Obama’s recent comments to the Business Roundtable included two blunders that showed his misunderstanding of the fundamentals of the cap-and-trade approach to reducing carbon emissions that is the centerpiece of his 2010 budget request.

Can clean energy investments carry their important share of the U.S. Recovery and Reinvestment Act load? Here’s a contrarian answer: It’s up to the utility industry and its regulators.

The Obama administration’s energy secretary, Dr. Steven Chu, has quickly become Dr. Who. As a recent New York Times article noted, Chu has repeatedly stumbled politically, demonstrating that being a Nobelist in physics is no qualification for the bumps-and-grinds of energy politics in Washington.

A zirconium oxide sensor technology originally developed for automotive applications could make in situ, simultaneous measurement of O₂ and NO_x a breeze for coal-fired power plants.

The flue gas desulfurization process requires the use of aggressive liquids that significantly shorten the life of typical construction materials such as metals and concrete. That makes fiberglass-reinforced plastic (FRP) the material of choice for many components in a typical flue gas desulfurization (FGD) system.

One of the key campaign promises made by our new president was that his administration would create five million new “green” jobs by spending $150 billion dollars over the next 10 years. There are serious and substantial reasons that this level of job creation won’t happen in the near future.

In a major decision aimed at preserving the air quality benefits of the program, a federal court on December 23 modified its July 11 decision to throw out the Environmental Protection Agency’s (EPA’s) Clean Air Interstate Rule (CAIR).

The new U.S. president will have a new set of priorities and regulatory policies that will affect the production and generation of electricity. The specifics of the new administration’s energy policy priorities were scant when this article was written, pre-inauguration, but the industry’s challenges are fairly well defined.
